Canola Seeding Depth and Row Spacing. 1  Canola seeds are small, and careful placement at a relatively shallow depth is required. 2  Best germination and emergence occur at 1/2 to 1 inch under conditions of good soil moisture.  Canola has difficulty emerging from crusted soil.
Serotonin plays a role in many brain processes, including body temperature regulation, sleep, mood, appetite, and pain. Problems with the serotonin pathway are linked to obsessive-compulsive disorder, anxiety disorders, and depression.he Dopamine Pathways. Dopamine is the neurotransmitter used by the reward pathway (also called the mesolimbic pathway, which is closely linked with the mesocortical pathway).
1: How does ecstasy work: serotonin pathways in the brain. The nerve pathway that is predominantly affected by ecstasy is called the serotonin pathway. Serotonin is a neurotransmitter that is synthesized, stored, and released by specific neurons in this pathway. It is involved in the regulation of several processes within the brain, including mood, emotions, aggression, sleep, appetite, anxiety, memory, and perceptions. Tell the students that you will show them how a chemical like serotonin can regulate these processes. First, describe how serotonin pathways innervate (connect to) different brain regions. Point to the cell bodies of the serotonin pathway that are located in the brainstem area the Raphe nucleus in pink).
